Episode 108 — Geolocation Rules: when geo blocking helps and when it backfires
Geolocation-based rules appear in CloudNetX scenarios as a simple control that can reduce exposure, but the exam expects you to understand its limitations and operational impact. This episode defines geolocation rules as policies that allow or deny traffic based on the inferred geographic location of an IP address, often used to reduce inbound attack surface from regions where an organization has no legitimate activity. The first paragraph focuses on why geo controls can help: they are easy to apply, can reduce noise from automated attacks, and can provide a coarse risk-reduction layer when combined with stronger controls. It also explains why they are not a primary defense, because attackers can use VPNs, proxies, and cloud infrastructure to originate from allowed regions, and because geolocation accuracy is not perfect. The episode frames geo controls as a supplemental measure best used when they clearly align with business boundaries and risk tolerance.
